Features To Consider When Choosing Best Weed And Grass Killer
a) Stage of Weed Growth
This process is referred to as emergence, and it's the stage at which you must apply the weed killer. There are two stages to consider when searching for the best weed killers:
- Pre-emergent weed killers: These are sometimes labeled as " weed preventers." They target and kill the germinating seedlings of weeds before they emerge from the soils as weeds. Generally, you can apply them to the soil of lawns or gardens before seeing the signs of weeds. These weed killers form a chemical barrier in the top layer of soil that stops the growth of seedlings underground, thus killing the weeds.
- Post-emergent weed killers: They are also known as herbicides and are used to control existing weeds that have already emerged from the soil. This type of weed killer can be applied to the leaves and/or stems of visible weeds in garden beds or driveway or sidewalk cracks; the chemicals will kill the weeds either by destroying the foliage or stems or traveling down to the roots and killing the whole root system.
This refers to the ability of a weed and grass killer to destroy weeds but leave surrounding plants unharmed.
- Selective weed killers: They destroy weeds but not turfgrass or other useful plants in the vicinity. Hence they are ideal for getting rid of, for instance, dandelions or thistles on the lawn or in a flower bed.
- Non-selective weed killers: These weed killers do away with weeds and any other plants in the application area. They can be used along the fence or pool or in a driveway or sidewalk cracks, where you won’t put essential plants at risk.
When searching for the best weed and grass killer, it's key to consider the translocation process. This refers to the movement of the product within a weed once it's taken up through the leaves, stems, or roots of the plant.
- Contact weed killers: This type of weed and grass killer doesn't move within a weed after entering it. Instead, they kill the weed by destroying the plant part to which you applied the killer, usually within hours to days of application. These are the best weed killers to use on annual weeds such as crabgrass, nettle, and chickweed, which are easier to kill than perennial plants and generally die when the foliage or stems are destroyed.
- Systemic weed killers: This weed and grass killer is absorbed into the weed and moves within the weed. It usually travels down to the roots, destroying the whole plant from the bottom up. Generally, you can expect results to take several days to weeks. Unfortunately, unlike contact weed killers, systemic weed killers usually won’t state the specific period of time it takes to kill weeds. These are the best weed killers for perennial weeds, such as dandelion, poison ivy, or ragweed, which are typically more difficult to kill because of their deeper roots.
Persistence measures how long after application a weed killer remains in the soil and provides weed control before reapplication.
Generally, you'll come across two types when shopping for the best weed killer.
Long-lasting weed killers remain in the soil and hinder new weeds from growing in the application for months or even a year. Therefore, they are an ideal choice for lawns or gardens where you need lasting weed control and prevent the germination of new plants you grow in the area for a longer period of time. However, it's advisable not to use this type of weed and grass killer in areas that you plan to grow new crops/plants soon.
Temporary weed killers deteriorate in the soil within a few days to weeks, forcing you to reapply the product often to keep the weeds at bay. This, however, allows you to quickly replant other plants in the area without interrupting their growth. These are the best weed killers for gardens where you plant flowers or vegetables soon or places where your weeds rarely grow, like gaps between paver stones in the yard.
e) Read The Safety Labels
Safety should always be a priority when handling weed killers. Hence shopping for the best weed and grass killer, it's important to pay attention to the safety labels, regardless of whether the product has chemicals in it or not.
Not all weed killers are made safe to use in the presence of pets and children; hence one should be aware of this before buying and applying the chemical. The labels will also guide you on how long to wait before it's completely safe to be in the vicinity again.
There's also the aspect of safety equipment in the form of protective gear that one should have when handling the chemicals. When shopping for the best weed killers, it is essential to remember to be safe and not exposed to dangerous chemicals that can cause serious health complications. Consider the best weed killer that comes with gear like nozzles and backpacks, and everything else that can help you spray the chemicals with minimal exposure.
Something worth noting is that though a product may be labeled " all-natural" or “organic,” it does not necessarily mean it’s safe in contact or around kids and pets.
Frequently Asked Questions About Best Weed And Grass Killer (FAQs)
a) How Does A Weed Killer Work?
There are three types of weed killers. Pre-emergent and non-selective.
Pre-emergent herbicides generally work on newly germinated weed seeds underground to stop the root system's normal development or prevent the plant from sending up new shoots.
Post Emergent Herbicides, affect foliage thus preventing photosynthesis. In addition, they are absorbed into the plant's root system, resulting in the termination of the weed.
Non-Selective Herbicides kill all plants they come into contact with. Roundup, a glyphosate-based herbicide, is a widely available type of non-selective weed killer.
Selective Herbicides only affect the growth of target species. Its commonly used for broadleaf weed control.
b) Are Natural Weed Killers Effective?
There's the option of opting for organic weed killers. The formulas range from homemade solutions of distilled vinegar to ready-made formulas with clove oil, citric acid, and other natural, active ingredients. Whether you use a homemade weed killer or purchase a natural weed killer, the key thing to note is these products are non-selective. This means that they will kill all plants within the application area.
c) Can You Use Weed Killer If You Have Pets?
Safety is a key concern if you have pets that frequently come into contact with your lawn. Many weed killers have long-lasting residual effects on the area they are applied to. Hence, pet owners should take caution when applying these products where their pets are likely to walk or play around as they could ingest the chemicals directly or by licking their paws and fur that have come into contact with the weed and grass killer.
Organic weed killer may be a better choice for pet owners since the compounds within it tend to break down faster and are absorbed by the ground. However, it’s still crucial to read the directions for use and consider the warning label on any products you use since the potential effects can vary based on the active ingredients of each formula.
